My car wont start..!
 
Hi i bought a other Shell for my car and i took off the parts from my car to put it in the new shell...! So when was the Time to start the engine , there is nothing going on.. The starter turns but it wont start.

Ive tested many things to try to find the problem: i have gas, but here is the problem: i only have ONE spark at the very begining on the leading coils and no spark at all on the leading.

My computer is good,( i have tried an other one and it did the same thing)

when i did the swap i kept all the sensors on the engine and took out the wires from the car with the engine so i havnt touched at the crank angle sensor.

I cant understant why would i have only one spark on each spark plug when i try to start..? Why would it fire once and then nothing..? If something was broken somewhere i suppose that nothing would happen ?

Please help me ive worked so hard for this project and my car was working well before so why would it not work .. The only difference between before and after is the body!

Thank you!!

Go ahead and check the CAS and see what that turns up while also checking the electrical plug connection is a good and clean one. Make sure the coils are properly bolted to the fender. Check the Green/Yellow wire at the leading coil for voltage w/key to on and see what it reads. Manually turn the engine over via the main pulley while reading the voltage output on this particular wire and see if it goes from 5 volts to 0 volts over and over. Make sure the grounds are in good shape especially the one on the UIM.
